Title: Brake actuator assembly including twin cam members
Inventor: GEE THOMAS A
IPC: F16D65/56
Filed: 1994-02-10
Granted: 1999-05-04
Abstract: A brake actuator assembly is disclosed for expanding internal shoe brakes in which a pair of brake shoes (17) are disposed with a brake drum (11). A pair of cam members (33, 35) are fixed to a pair of cam shafts (41,43) and are operable to engage the brake shoes by means of cam follows (37,39), in response to a brake input (56.55). The cam shafts (41,43) are timed relative to each other by a pair of gears (73,75). The disclosed actuator assembly ensures that the cam members rotate through the same angular magnitude, but the amount of torque transmitted to each cam is determined by the braking force required for the respective brake shoe. The disclosed actuator assembly provides for substantially greater lift, for longer shoe wear life, without taking up as much space in the radial direction as would an equivalent S-cam arrangement.

Abstract: In a continuous screw conveyor or auger, the rotat-able screw member (12) comprises a helical radial blade (28) (known as "flighting") which is preferably carried on a central driving shaft (26). The flighting (28) is formed by rolling a rectangular metal strip of uniform thickness be-tween a pair of opposed, preferably offset, conical rolls (56, 58). In contrast to prior art rolls which have similar unstepped conical rolling surfaces, and produce a helical blade of which the radial thickness reduce progressively from the inner helical edge (30) of the blade to the outer helical edge (32), the present invention provides on at least one of those rolls (58) a stepped conical rolling sur-face (94) formed so as to exert less rolling pressure on an outer portion of the helical blade (28) being formed, there-by to produce a blade in which the outer portion is of a thickness (preferably uniform) which is no less than and preferably greater than that of an inner part of the blade lying immediately radially inwards thereof.

Title: Device for degassing thermoplastics
Inventor: BACHER HELMUT
IPC: B29C48/74
Filed: 1994-06-08
Granted: 1998-10-20
Abstract: Disclosed is a device for degassing thermoplastics, the device having a first worm-conveyor zone for feeding in the material to be treated.  The plastified plastic material flows out of the housing of this worm-conveyor zone through a connecting channel to a filter and from there through an inlet aperture into the housing of a second worm-conveyor zone which conveys the material to an outlet.  Lying between the two equiaxial worm-conveyor zones is a seal zone which prevents the filter from being bypassed.  Immediately downstream of the inlet aperture is a baffle barrier which forces the stream of plastic into a tubular shape.  The baffle barrier can be adjusted relative to the inlet aperture in the longitudinal direction and has a cross-section which tapers towards the second worm-conveyor zone.  This shortens the migration path for gas bubbles from the plastic material and thus facilitates the degassing through the degassing aperture.

Abstract: A valve mechanism for a needleless connector employs a deformable piston having a piston head of elliptical cross-section with a marquise-shaped bore formed along its longitudinal axis wherein the major axes of the respective generally elliptical shapes are oriented perpendicular to one another. The piston head is captured within the connector housing and is reciprocal between a section of reduced diameter adjacent the connection port and a section of enlarged diameter. Constraining the piston head into the section of reduced diameter causes the elliptical bore to be squeezed shut while positioning the piston head in the section of enlarged diameter causes the piston head to relax and assume its natural elliptical shape, while the boresimilarly regains its natural open shape to provide a fluid path therethrough. A compressible or extendible section affixed to the piston head serves to bias the piston into the section of reduced diameter. A tapered section of the piston contacts the housing to secure the top of the piston flush with the top of the housing for ease in cleaning.

Abstract: A door lock has a latch which is rotatable from a retracted position to an extended position by means of a linkage. A safety button extends from the latch when the latch is retracted. The linkage cannot be moved unless the safety button has been pressed, which occurs when the door is adjacent the door frame. This prevents the latch from extending and so damaging the keeper in the door frame. The linkage also has a notch which cooperates with a tang projecting from the housing. The tang an notch prevent the latch from being rotated from the extended position to the retracted position except by operation of the linkage. This feature makes it difficult to force the lock open without a key. In addition, one or more remote locks may be added to the main lock. With two remote locks it is possible to provide three anchor points for a door. Further, the remote locks are individually adjustable so that the reach of the latches can be varied to suit the configuration of the door frame or door, and so to accommodate irregularities due to installation or warpage. One of the remote locks can rotate in the opposite direction from the main lock so that the door cannot be lifted off its track.

Granted: 2001-04-10
Abstract: There is provided an improvement for a railroad freight car for transporting containers.  The car is of the type having spaced apart side structures, opposed end structures and a floor structure, all of which together define a well for receiving a plurality of containers.  The well has a longitudinal direction substantially aligned with the direction of travel of the car and a transverse direction substantially normal thereto.  The floor structure of the car has a container support within the well which provides a container support surface.  The improvement comprises a container stop provided with the container support, the container stop having an extended position and a retracted position.  The container stop is biased to the extended position by a biasing component.  The extended position is defined by the container stop extending upwardly from the container support surface to present two stop surfaces within the well.  The stop surfaces arrest the longitudinal translation of two of the containers when same are respectively located longitudinally on each side of the container stop and are respectively seated on the container support surface.  The retracted position is defined by the container stop being retracted with respect to the container support surface when a container is placed onto the container stop, such that the stop surfaces are not presented within the well.  The improvement also comprises a container guide associated with the container stop.  The container guide is provided in one of the side structures, and includes a deflector which extends within the well in the transverse direction.  The deflector longitudinally guides a container within the well as the container is being placed therein.  The deflector is dimensioned and positioned with respect to the container stop so as to prevent both of two containers from seating onto the container stop together when each of the two containers is placed in succession within the well of the car.
